I’ve used both A23 and Quill rims with SBH tires. Also Pacenti Brevet. In my experience, they are all good rims, with some differences which may or may not be significant to you.
In order of depth of experience, I’ve used A23 rims for many years, both symmetrical and offset spoke bed. Long enough to wear through several brake tracks (10’s of thousands of miles). I’ve got 4 in current use, and have worn through or replaced about 6 others. I’ve got 2 Brevets in current use, and have replaced one. I’ve got 4 Quills in current use, all of which are relatively new, so none have been replaced yet.
All of these rims are about equal in terms of fitting tires. With tubeless rim tape and good technique, I can mount and dismount RH tires without tools. Each will seat the bead on a RH TC tire without the need to drastically over inflate. Sometimes it takes a little time or bead lube before the tire fully seats, typical of many modern tire-rim combinations.
Stiffness: The A23 is the most flexible of this bunch. If you mate this rim to a highly dished rear hub, it’s a very good idea to use the offset spoke bed version. You’ll reclaim a small but critical amount of spoke tension on the non-drive side, making the wheel more robust and improving its longevity. The Quill is the stiffest, due to its deep section. The increased radial stiffness makes it play better on a highly dished wheel. A radially stiff rim helps keep the NDS spokes from momentarily going slack under transient loads. It’s that momentary slackness that kills spokes.
Width: Quill is about 1-2 mm wider than the Brevet, which in turn is about 1 mm wider than the A23. SBH tires work fine on all of these rims. The tire sidewalls may be slightly more vulnerable on the wider rim.
Ease of building and truing: the Quill has the edge here. They build up very straight and true, with exceptionally even tension, even at the rim joint. That said, none of these rims are bad in this regard.
Overall I’m currently favoring the Quill. The Brevet has a more classic look, but their relative flexibility and symmetrical spoke bed makes them a less robust choice for a rear wheel with a 11-speed compatible hub and a heavier rider. For a less dished rear wheel, or a lighter rider, they are fine.
